Spécialités
Intérêts scientifiques
Mes recherches actuelles concernent d'une part les mécanismes moléculaires par lesquels les neurotransmetteurs ou les neuromodulateurs, notamment la dopamine, agissent sur les neurones cibles. Nous nous intéressons plus particulièrement dans ce cadre aux réactions de phosphorylation de protéines responsables de la transduction du signal. D'autre part, nous étudions les protéines impliquées dans les contacts entre les axones et les cellules gliales myélinisantes.
